FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 542,555, dated July 9,1895.

Application filed January 24, 1895. Serial No. 536,130. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM H. DEAN, acitizen of the United States,residing at West Berkeley, in the county of Alameda and State ofCalifornia, have invented certain new and useful Improvements inSash-Locks; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to manufacture and use thesame.

This invention relates to useful improvements in sash-locks of thatclass in which provision is made for the locking together of themeeting-rails of sashes when the window is in a closed position.

The present invention has for its objects, among others, to provideanimproved construction that is simple and effective and can be easily andreadily applied and operated. The parts are so arranged as to be readilyassembled, not liable to derangement, and positive in their action. Thelock is especially designed for itssecurity and its structural economy.j

Other objects and advantages of the invention willappear in thefollowing specification and the novel features thereof will bespecifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the numerals of reference marked thereon, form a part ofthis specification, in which- Figure 1 is a perspective view of myimproved lock in a locked position. Fig. 2 is a similar view showing thelock open. Figs. 3 and 4 are details. Figs. 5, 6, 7,and 8 are detailviews of a modified form of lock used in connection with-my invention.

Like numerals of reference indicate like parts throughout the severalviews.

way of the lower sash 9. The other or rear end of the latch 4is turnedupward and back to form apartial housing for the rear end of the lever8, and for another purpose which will be explained hereinafter. Near theouter end of the latch 4 is an L-shaped slot 10, which is adapted toengage the tapered headed lug 11 formed on a plate 12 secured to theupper rail of the lower sash 9.

The lever 8 is pivoted to thejpin 2 directly over the latch 4. On theupper surface of this lever 8 is a cam 13, which is adapted to engageand rest against the inner edge of the turned-over portion 14 of thelatch 4, while on the lower surface of lever8 is formed a second cam 15,which engages with the projection 16 on the latch 4. The outer end ofthe lever 8 is formed with the contracted portion 17 to correspond andengage with the cut-away portion 6 on the latch 4. A knob 18 is providedto operate the lever 8.

' The operation of my device is as follows: To look the upper and lowersash together,

the parts having beenpositioned as shown in Fig. 2 by the operation ofunlocking, the lever 8 is operated in the direction of the arrow 19.

'When the lever and latch 4 have been turned the window, the slot 10permitting said latch to move on the'pin 2. It will be readily seen thatin this position it is impossible to revolve the latch in eitherdirection without first moving it forward until the lug 11 is disengagedfrom the longitudinal leg of the slot 10. The lever 8 is held in theposition shown in Fig. 1 by the cut-out stop 21.

To unlock the device the lever 8 is raised out of cut-out stop 21 andthe operation reversed. The cam 15 engages with the projection 16 on thelatch 4, forcing the same forwardand out of engagement of the headed lug11. At the same time the beveled portion 31 of'the lever 8 encountersthe beveled corner 32 of the lug 11 when it is raised and theprojection. 17 enters the cut-out portion 6. The lever 8 and latch 4 arenow practically one, and they are turned on the pivot 2 in the directionof the arrow 22 until they assume the position shown in Fig. 2. Thus thelower sash is now free to be raised or the upper sash to be lowered.

In Figs. 5, 6, and 7 is shown a spring-lock, which is applied to theupper railof the lower sash in place of the plate 12 and headed lug 11,the lug 11 taking the place and doing the same work in relation to theremaining parts of the lock described above as the stationary lug 11. Itcomprises a casing 23, having therein a spring-pressed bolt 24. Thisbolt 24 Works in an opening 25 in the front of the casing 23 and engageswith a corresponding opening 26 in the lower rail of the upper sash.(Shown in Fig. 8.) The rear end of the bolt 24 projects through anopening 27 at the rear of the casing 23 and is formed' with a shoulder28. Pressing upward against the lower sur fac'eof the bolt 24 is aspring 29, while a slot 30 is provided for the lateral movement of thebolt 24. It is evident that the parts of this modification beingpositioned, as shown in Fig. 6, it is necessary to exert a downwardpressure on the lug 11 until the shoulder 28 clears the rear of thecasing before the bolt 24 can be forced backward and unlocked, whiletheonly operation in looking is to force this lug 11" and bolt 24 forward,and the shoulder 28 immediately springs upward into the position shown.When the parts are positioned, as indicated, and locked, the lever- 8and latch 4 are operated as above, and it is manifest that the lug 11fulfills all the ends of the lug 1'1 and in addition adds security tothe entire look, as even were the lever 8 and latch 4 forced into theposition indicated in Fig. 2,

known the operation and the advantages of the same will, it is thought,be readily understood.

Having thus described my invention, what I claim, and desire to secureby Letters Patout, is

1. In a sash lock the combination of a latch or look with angle L-shapedslot 10 in one side thereof, and a slot 3 near one end, and a turnedover-portion 14, a lug ll withtwhich the opening 10 engages, and a lever8, all arrangedsubstantiall-y' as and for the purpose set forth.

2. A sash lock comprising a latch or look 4 provided with an L-shaped'opening in one side, a longitudinal slot 3, turned over portion 14, andflange 5 having a cut-out portion 6, an operating lever 8 having at itsinner end the cam surfaces 13 and 1'5, and at its outer end a reducedportionv anda knob 18, substantially as and for the purpose set forth.

3. In a sash lock, the combination of a latch or look 4 having anL-shaped opening 10 in one side thereof, a lever coacting with saidlatch or look, and a spring pressed button having a bolt attachedthereto, said button being adapted to engage with said opening 10,substantially as described. r

In testimony whereof I hereunto set my hand in presence of twowitnesses.
